Cat?� C32B HRC Diesel Engine

Building on the legacy of the C32, the C32B features strengthened
performance critical components like cylinder head, block,
crankshaft, pistons, rods, and main bearings. Its simple,
maintenance free diesel oxidation catalyst (DOC) aftertreatment
meets U.S. EPA Tier 4 Final, EU Stage V, and other equivalent
emissions standards

The C32B uses a dual-can diesel oxidation catalyst (DOC) aftertreatment. This maintenance-free, passive aftertreatment solution eliminates the need for thermal management or regeneration. The C32B does not require diesel exhaust fluid (DEF), helping minimize total fluid consumption and eliminating the need for any DEF infrastructure (DEF tank, DEF pump, heated DEF lines, additional electronics, and DEF storage on the jobsite). DOC-only simplifies the aftertreatment solution, helps minimize overall package size, and reduces operation costs.
